This is joint is important in maintaining proper alignment and strength of the joint. Lisfranc ligaments hold the bones at this joint together.

The sooner this injury is treated, the less damage is done to surrounding bones, ligaments, and cartilage. The surgeon will examine the foot and ask questions on how the injury occurred. X-rays or other imaging devices are necessary to fully evaluate the injury and its severity.
Types of Injuries
Sprains- this is the stretching of a ligament resulting in a weakened foot
Fractures- a break in the bones in the Lisfranc joint
Dislocations- the bones of the Lisfranc joint have been forced to move out of their normal positions
Treatment

Immobilization– foot is placed in a CAM walker or cast, crutches may be used to avoid weight and pressure on the foot
Oral medication– Nonsteroidal anti-inflammatory medications (NSAIDs), such as ibuprofen, help reduce the pain and inflammation.
Ice and elevation– Reduce swelling by icing the affected area and keeping the foot elevated
Physical therapy– After the swelling and pain have subsided, physical therapy may be prescribed to rebuild strength
Surgical treatment may be needed if injury cannot be fixed using immobilization and physical therapy.
